MetaS: The Difficult Pivot from AI Writing Assistant to AI Search
Founded: Yan Lipeng, Li Xiyao, Wang Hu · Shanghai MetaS Network Technology Co., Ltd.
Key Fields
FIELD STAMPSOrigin
In 2018, while developing legal translation and contract review tools, the team discovered that Chinese lawyers and legal professionals were extremely inefficient at document proofreading and grammar correction. At the time, Grammarly was thriving globally, but there was no Chinese equivalent. In 2019, Yan Lipeng led the team to launch 'MetaS Writing Cat' (秘塔写作猫), a proofreading and polishing assistant for Chinese writing, with the initial goal of solving deep-seated inefficiencies in official document and legal drafting.
Milestones
Turning Points
- September 2019: Launched the web version of MetaS Writing Cat, finding its first PMF in the domestic Chinese writing assistance track by attracting students and copywriters with free features.
- End of 2022: After the release of ChatGPT, massive user churn occurred. Yan Lipeng admitted in a 36Kr interview that Grammarly would eventually be replaced by ChatGPT, forcing the team to rethink its technical roadmap.
- March 2024: MetaS AI Search was officially launched, focusing on an ad-free, direct-answer experience. It gained millions of visits in the first month, marking a complete transition from a writing assistant to a generative AI search product.
- 2025: As general-purpose large model vendors entered the AI search track, the company was forced to refocus on legal and academic vertical search, shrinking the team to 60 people and re-evaluating its competitive moats.
Failures & Pitfalls
- 2020: The paid conversion rate for Writing Cat remained below 3% for a long time, and the low ARPU from university students made it difficult to sustain the team, with early annual revenue under 1 million RMB.
- First half of 2023: The company lost nearly 40% of its paid users due to the impact of ChatGPT. Attempts to launch full-process AI writing features failed to meet expectations, leading to a sharp increase in cash flow pressure.
- 2025: Server and inference costs exceeded millions of RMB per month. Following the entry of general-purpose model vendors, the company was forced to downsize and remains unprofitable, continuing to rely on external financing to survive.
关键成功要素
- The product in the Writing Cat era was too dependent on a single correction feature and lacked deep workflow integration, making the cost for users to switch to ChatGPT almost zero.
- The choice of an ad-free model for AI search effectively acquired users but severely compressed monetization space, making it difficult to alleviate the pressure of marginal server and inference costs.
- The high barrier to entry in legal and academic fields became the core foundation that MetaS could defend, whereas writing users were the first to be fully cannibalized by general-purpose models.
- The team's choice to maintain a disciplined financing pace rather than burning cash aggressively, along with cautious cash flow management, was the key reason the company survived long enough to pivot.
Lessons
- If a vertical AI tool is merely a wrapper for general-purpose model capabilities, it quickly loses its value once large model vendors enter the same scenario.
- Users acquired through free services often have extremely low loyalty and will churn immediately when faced with stronger free alternatives; this type of user base is not a foundation for long-term survival.
- The AI search track appears to have a low barrier to entry but is actually extremely costly. The ad-free model requires a massive user scale to cover inference costs and support commercialization; small and medium-sized teams must constantly evaluate their viability.
- Maintaining a lean team and cautious cash flow management is a prerequisite for small and medium-sized AI startups to survive the wave of large models; blind expansion only accelerates failure.

Competitors / Peers
In the domestic market, MetaS AI Search faces direct competition from Kimi (Moonshot AI), Zhipu Qingyan (Zhipu AI), and Quark AI Search. These three are deeply backed by large model vendors or internet giants, giving them significant advantages in inference costs and data resources. In the overseas market, it benchmarks against AI search platforms like Perplexity and You.com. Meanwhile, competitors from the MetaS Writing Cat era, such as Grammarly and WPS Lingxi, are now leveraging large model capabilities to continuously erode the Chinese writing assistance market, creating a severe competitive landscape for vertical tool entrepreneurs.
